SCRAPER FOR WRINGEBS.

original application flied February 6, 1926, Serial No. 86,600. Divided and this application filed September 20, 1927.

This invention relates to clothes wringers, and particularly to an improved scraping at.- tachment therefor, and has for an object to provide an improved construction whereby the wringer may be used intermittentl or continually, and the clothes prevented t iom Wrapping around the squeezing rollers.

Another object of the invention is to provide a system of scrapers in connection with a wringer having a safety device or without the safety device, the scraping structure being such as to prevent the clothes passing through the wringer from adhering to the rollers.

Afurther object, more specifically, is to provide a scraping attachment for wrmgers, wherein the scraping members are either weight actuated or spring actuated.

This application is a divisionalapplication of my rior application, Serial No. 86,600, filed Fe 6, 1926.

With the above recited and other objects in view, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claims are expressed.

In the accompanying drawings Figure 1 is a side view of a wringer with scraping structures embodying the invention shown applied thereto.

Figure 2 is a rear view of part of the wringer shown in Figural, with the scrapers embodying the invention shown associated therewith.

Figure 3 is a top plan view of the structure shown in Figure 1.

Figure 4 is a sectional view through Figure 3, approximately on line 4-4.

Figure 5 is a detail fragmentary view similar to the structure shown at the left in Figure 4 but illustrating a modified arrangement of scrapers.

Figure 6 is a fragmentary sectional view similar to Figure 4, but showin a modified form of scrapers wherein weig ts are used instead of springs.

In applying an embodiment of the invention to a wringer, it will be noted that the same may be applied to any of the wringers Serial No. 220,792.

now in common use, or to a wringer of the kind shown in iny co-pending application, Serial No. 86,600.

Referrin to the accompanying drawings by numera s, 1 indicates a support of any so desired kind on which a wrin er 2 is mounted. The wringer 2 is provide with brackets 3 which may be specially secured thereto by screws or otherwise and which fit into notches in the extensions 5 on the side bars 5 of frame 6. The frame 6 is provided with two side bars constructed as shown in Figures 1 and 2 and with suitable connecting and bracing bars 7 held in place by suitable nuts. 7 It will be noted from Figure 4 that nuts are provided on the bar 7 for spacing the side bars of frame 6. Rollers 8 and 9 are rotatably mounted on the frame 6, roller 8 havin end plates or flanges 10 for holding the be t 11 in place and also for assisting in guiding the clothes as they are fed through the device. The belt 11 may be a combination of canvas and rubber or other desired material, and is held taut by suitable springs so '12 arranged in sockets 13 on the respective side bars of frame 6. These springs act on journal blocks 13', which press'against the shaft 14 supporting the roller 8. A cross bar 15 is connected in any suitable manner 5 with the extensions 5, said cross bar suprorting a scraper 16 and a uiding plate 1 he scraper 16 may be ma e of a combination of rubber and canvas or other desired material and acts to in a certain sense, scrape 0 or prevent clothes from following the belt 11 around the roller 9. This scraper insures all of the clothes passing over belt 11 en ging the plate 17 and then the roller 18 o the wringer 2. The plate 17, together with the 5 scraper 16, acts as a bridging structure for bridging the space between the rollers 9 and 18.

In order to prevent thin pieces of clothes or in fact, any piece of clothes from adhering to the rollers 18 and 18, there are provided scrapers 19 and 20 made of any deslred material, but preferably of rubber. These scrapers are clamped by bolts or otherwise otally held in place by the respective pivotal pins 25 which hold the swlngm frame 26 on an extension 27 of frame 6. retractile spring 28 is connected to frame 6 for each of the arms 21 and at one end is connected to these arms for normally holding the scraper 19 against the roller 18. Each of the arms 21 is also provided with a forwardly extending portion 29 (Figure 1) formed with a. bent over section 30 adapted to be engaged by the thumb when it is desired to raise the scraper 19 off of the roller 18'. The arms 22 are yieldingly held against the roller 18 by springs 31 connected to the respective arms and to the cross bar 15. Each of the arms 22 is provided with a forwardly extending section 32 which may be engaged by the hand of the operator and moved upwardly for swinging the scraper 20 away from roller 18. It will thus be seen that as the clothes are fed through the wringer, the scrapers 19 and 20 contlnually function to prevent any of the clothes from adhering to the rollers and, consequently, causing the rollers to continuall function in a desirable manner. It will a so be evident that the scrapers 19 and 20 may be connected to a stationary part of the wringer instead of to the frame 6 as illustrated in Figure 5. From this figure, it will be noted that the scrapers function to remove the clothes from the rollers but are pivotally mounted on the wringer 2 and held 111 operative, position by suitable sprin In providing the scrapers, it Is aimed to produce a very practical construction for wringers of any desired kind which will not dig into the wringer rollers, and which will not appreciably wear said rollers. In the present construction, the scraper is preferably made of a ood grade of rubber which will bend over s ight-ly when the wringer is in motion, and will cause the scraper to always present a sharp or straight edge to the rollers. The springs act to provide the desired pressure so that when the wri er is in use, the edge ofthe scraper will be eflected and slightly bent over to produce a sufiicient scrapin action that Wlll stop a thread or even thin tissue paper from winding around the rollers. This action will, of course, keep clothes from winding around the rollers and, consequently, cause the very desirable as it has the desired characteristics and will wear an appreciable time.

In Figure 6, a modified form is presented wherein the arm 21' is made comparatively; heavy so that the scraper 19 will act throug gravity instead of spring 28. The arm 22 is provided with a weight 32 which may be athustably positioned so as to give varying pressures on the scraper 20. The weight of the res ective parts is such that the scrapers 19 an 20 will be deflected or bent over slightly at their contact ed es in similar manner to the action pro uced b the springs28 and 31. In this form of t e invention, preferably the scraper 19 is at the highest point on roller 18" and scraper 20 is at the lowest point on roller 18.

What I claim 1s:.

1. In a clothes wringer rovided with a pair of squeezing rollers, a at rubber scraper for each roller, a swinging arm for each scraper, said arms being pivoted so that the scrapers will move in a direction substantially toward the center of the rollers with the scrapers extending substantially radially, and means acting on the arms for producing suflicient pressure thereon to cause the edges of the scrapers to bend when the rollers rotate whereby an efiicient scraping action is secured and articles are prevented from adhering to the rollers.

2. In a clothes wringer provided with a pair of squeezing rollers, a scraping structure associated with each roller, each of said scraping structures including a thin fiat flexible scraper blade, a pair of holding plates carrying said blade, means for removably clampin said blade to said holding plates, a pivotal mounted arm connected at one of its on with said lates whereby the blade may swing towers and from one of said rollers, and a spring acting on said arm for causing the plates to press said blade against said roller.

Signed at Detroit in the county of Wayne and State of Michigan, this 17th day of September, A. D. 1927.
